Please explain

it just as it is :)) When they were kids, they both wished Yeon Woo's parents were not there anymore so they got their wish granted from the black room full of mirrors, from that moment on, I'd like to think that they were somehow cursed with their dark malice selves, and can summon/control(I think?) the ghosts from the mirrors (bloody hands :'>) whenever and do whatever they wish them to do. I do think they can't control them fully, like sometimes the bloody hands would come out and kill random people, like in the cinema, so maybe now wherever they go, more massacre or evaporate incidents will occur :'>>>

I think Yeonwoo killed that person in the cinema (and on the street) on purpose to try to remind Jun of the past/trigger his memory. So, Yeonwoo was in control of the hands then too.

Oh. My. Gosh. If I could hug you rn I would. I was so confused at the whole “other selves” part but you explained it so perfectly. THANK YOU!! xoxo

This makes so much sense too bc yeonwoo seemed pretty desperate at those points. Thank u too!!!! xoxo

lol that makes more sense :'> totally messed up though ╮(￣▽￣)╭
